The all-new 2016 Subaru Impreza, already spied testing in heavy camouflage, has been previewed in concept form at the Tokyo Motor Show today. Recent history suggests we can expect the Impreza concept’s sharp lines to be softened dramatically in the transition to production, but it is likely that the show car’s key themes will be retained. As with the new Forester-teasing Viziv Future concept, the Impreza 5-Door Concept showcases a tightly tapered profile, covered end-to-end in chiseled character lines. Subaru’s familiar six-point grille dominates the front end, flanked by an extra sharp take on the brand’s new hooked-LED headlight styling. The Impreza show car sits low on large 19-inch alloy wheels, but – short of the WRX badge returning to the Impreza range – we can likely expect all variants to wear smaller hoops and a taller suspension package. In concept form, the Impreza measures 4400mm long, 1800mm wide and 1440mm tall, making it 14mm shorter, 60mm wider and 25mm lower than the current production Impreza. Again, though, we can expect the final new Impreza design to come closer to the dimensions of the existing model – and in fact our spy photos confirm. Mechanical details for the new concept and its production offshoot have not been revealed, although Subaru has spoken at length of its plans to introduce electric assistance to its drivetrains, mainly in the form of an advanced new all-wheel drive system. Subaru has dubbed the system simply ‘Symmetrical Motor All-Wheel Drive’, which again sees the rear axle driven electrically, this time by just one motor. The new system means the conventional propeller shaft design is gone, while also introducing a flat floor for greater interior comfort and space. The technology is yet to be confirmed for the new Impreza, but it is likely not far away from appearing in showroom models. Watch for the new Impreza to make its global debut in the coming year.
